Can cooling tower mechanical inspection move from a fixed interval to a condition-based check?

Partly: part of the task converts to a condition and part stays on the calendar. The mechanical items convert; the fill and basin clean and disinfection are tied to the legionella regime and stay on its interval.

What condition would trigger cooling tower mechanical inspection instead of the calendar?

Fan vibration above baseline, gearbox oil condition, basin level control cycling, approach temperature above design

What reading proves cooling tower mechanical inspection was done?

Fan and gearbox vibration, gearbox oil level and condition, wet bulb approach, basin level. Observed by: Vibration sensor on the fan and gearbox; controller readings for approach and level.

What evidence does cooling tower mechanical inspection produce for an ISO 55001 or ISO 45001 audit?

Vibration and approach trend, and the clean and disinfection record under the water treatment programme

Cooling tower mechanical inspection

The fan and gearbox are ordinary rotating equipment and convert like any other. The basin clean is a public health task and stays.

asset class

Condition that replaces the interval: Fan vibration above baseline, gearbox oil condition, basin level control cycling, approach temperature above design
Reading that proves it: Fan and gearbox vibration, gearbox oil level and condition, wet bulb approach, basin level
Why the interval stays: The mechanical items convert; the fill and basin clean and disinfection are tied to the legionella regime and stay on its interval.
Evidence an auditor accepts: Vibration and approach trend, and the clean and disinfection record under the water treatment programme
First move: Treat the tower as two registers: a mechanical one that converts and a water hygiene one that does not.
